Failure due to new paramiko (4.0.0)

[nathanIL]

Getting:

from Exscript.protocols import SSH2, Telnet
  File "/home/builder/.local/lib/python3.9/site-packages/Exscript/__init__.py", line 33, in <module>
    from .key import PrivateKey
  File "/home/builder/.local/lib/python3.9/site-packages/Exscript/key.py", line 27, in <module>
    from paramiko import RSAKey, DSSKey
ImportError: cannot import name 'DSSKey' from 'paramiko' (/home/builder/.local/lib/python3.9/site-packages/paramiko/__init__.py)

when forced to use paramiko 3.5.X on requirements.txt, it works fine.
